| Abstract: |
| The rapid qualitative analysis methods of doping latex were studied.The contrast test of fresh latex and the doped latex of starch，urea，dusts and lime powder with mass fraction of 0.05 were carried out.The results showed that，when the latex without solidification and pressing was directly dried by using the disc automatic sampling hot box type latex sample dryer，the color and texture of the doping latex film were quite different from that of the fresh latex film.The latex were conglomerated under the effect of acetic acid and compressed into sheet rubber with gel sample sheeter.Under the conditions of same amount of acid，sheeter pressure，sheeting thickness and sheet rubber size were consistent，the physical properties such as tear point and tensile length of sheet rubber of doping latex were obviously lower than that of sheet rubber of fresh latex.The drying test by disc automatic sampling hot box type latex sample dryer or the physical property test on sheet rubber of latex could be used as field rapid qualitative analysis methods for the quality of doping latex，and applied in the condition of simple operation，shorter time，and simple and portable equipment. |
